Service overview
What this service covers
Diagnose, maintain, and replace supported commercial make-up air equipment and controls. For commercial buildings and managed facilities, the useful scope depends on the installed equipment and the conditions present at the property. Indoor-air and ventilation improvements should address pollutant sources, outdoor-air delivery, filtration, moisture control, airflow, maintenance access, and compatibility with the existing HVAC system.
Service begins by confirming the request, equipment identity, building use, access, operating history, and the result the owner or manager needs. Green Flow then defines the appropriate maintenance, diagnostic, installation, documentation, or replacement path based on the conditions found and the approved scope.
- Review airflow, coil condition, defrost operation, controls, sensors, and outdoor conditions before ice is treated as the cause by itself
- Clarify the comfort, odor, moisture, ventilation, or filtration concern
- Review existing filters, outdoor-air paths, exhaust, drains, and accessible equipment
- Confirm airflow direction, equipment compatibility, and maintenance requirements
- Avoid claims that a single device removes every indoor-air contaminant
- Verify operation and explain filter, cleaning, or moisture-control upkeep
- Confirm the requested outcome and the equipment or areas included in the scope
- Document completed work, observed conditions, and useful next steps

What information helps with a make-up air unit service request?
Share the property type, equipment model if available, current symptoms or project goal, photos, access details, and preferred timing. This helps Green Flow route the request and prepare the right next step.
Does make-up air unit service start with an on-site assessment?
The appropriate first step depends on the equipment and request. Green Flow may begin with equipment identification and an on-site review before confirming repair, maintenance, installation, or replacement scope.
Can Green Flow coordinate make-up air unit service for occupied properties?
Access, occupants, tenant impact, operating schedules, and site constraints can be discussed during planning so the approved work can be coordinated appropriately.

The repair person came quickly and was super efficient and polite, and showed me what to do next time. He gave my dog a quick pay and was off again.
